Seoul: Today in Korean history, South Korean and U.N. forces successfully recaptured Seoul, three months after the city was taken by North Korean invaders at the onset of the Korean War. The North Koreans managed to regain control of Seoul four months later, but were eventually pushed back by U.S.-led allied forces.

According to Yonhap News Agency, in 2009, a significant event took place as hundreds of South and North Korean relatives were reunited on Mount Kumgang, North Korea. This marked the first government-arranged reunions in two years, following a halt in such events in 2007 due to strained inter-Korean relations.

In 2010, South Korea achieved a historic victory by winning the U-17 Women's World Cup for the first time. The team secured their victory against Japan with a 5-4 win in a penalty shootout held in Trinidad and Tobago. This triumph also represented South Korea's maiden championship title in any FIFA-sponsored tournament, for both men's and women's football.

A year later, in 2011, a South Korean adoptee made history by winning a seat in the French Senate during the country's parliamentary election. This achievement marked the first time an ethnic Korean advanced to France's top political body.

In 2014, the boards of Hyundai Motor Group affiliates approved a major deal to purchase a prime land lot for 10.55 trillion won (US$10.09 billion). The consortium, made up of Hyundai Motor Co., Kia Motors Corp., and Hyundai Mobis, acquired the plot in southern Seoul, making it one of the most expensive land deals in South Korea's history.

Two years later, in 2016, South Korea and the United States conducted a combined maritime exercise in the East Sea. This exercise was part of a demonstration of force in response to North Korea's provocations, which included conducting its fifth and most powerful nuclear test earlier that September.

In 2017, South Korea unveiled an ambitious 7.2 trillion-won plan aimed at reducing fine dust by 30 percent by 2022. The plan included measures such as closing aging coal-powered plants, replacing old diesel cars, and introducing a new levy on emitters.

Finally, in 2018, South Korean President Moon Jae-in and U.S. President Donald Trump discussed potential incentives for North Korea's denuclearization efforts during a bilateral summit in New York. Their discussions apparently included plans for a second U.S.-North Korea summit.
